How to rename multiple file extensions at the same time?

Question

I already referred this post and post

I have my filenames like as shown below (1 set contains 3 related files). In my directory, I have 40 set of files (meaning 120 files). All the 40 sets have 3 files with same file extension

Set 1

Test_t5.version9.info.gz
Test_t5.version9.dose.vcf.gz.tbi
Test_t5.version9.dose.vcf.gz

Set 2

Test_t5.version12.info.gz
Test_t5.version12.dose.vcf.gz.tbi
Test_t5.version12.dose.vcf.gz

Only the version number in file changes across different sets.

Now, I would like to rename my files like as shown below

Set 1

Test_t5.version9.info.gz
Test_t5.version9.dose.vcf.gz.tbi
Test_t5.version9.dose.vcf.bgz            #see the change here from `.gz to .bgz`

Set 2

Test_t5.version12.info.gz
Test_t5.version12.dose.vcf.gz.tbi
Test_t5.version12.dose.vcf.bgz            #see the change here from `.gz to .bgz`

I tried the below but guess am making mistake while executing the command in the shell.

 rename 's/dose.vcf.gz/dose.vcf.bgz/' Test_t5.version*.dose.vcf.gz

Basically modify the file extension for only one file in each of the set. You don't have to worry about Set 1 or Set 2. That was for you to understand that how our data is grouped.

Can you help please?

That command looks fine to me. Does it produce any output or error messages, or does it silently do nothing? — Thomas, Sep 10 '20 at 14:56

It looks like you are just wanting to do:

for file in *.vcf.gz; do mv "$file" "${file%.gz}.bgz"; done

@Thomas You can test what files it will touch by changing the command slightly: `for file in *.vcf.gz; do echo "$file"; done`. It should not touch any `.info.gz` files. – 0x5453 Sep 10 '20 at 15:00
It will not touch files with `vcf.gz.tbi` extension. Am I right? – The Great Sep 10 '20 at 15:03
I only like to rename files with extension `vcf.gz` to `vcf.bgz` – The Great Sep 10 '20 at 15:03
btw, upvoted for the help. Will accept the answer soon once I try it. Currently not at my desk. but can help me with my questions in the comments – The Great Sep 10 '20 at 15:04
Correct, the `*.vcf.gz` glob will not match names ending in `vcf.gz.tbi` – William Pursell Sep 10 '20 at 15:07
